Leading fire and security products supplier, ESP, has added a new fire isolator switch to its growing fire protection range. With a legal requirement in place to ensure all new fire alarm systems in the UK are fitted with a mains isolator switch, ESP’s latest addition meets the requirements of the BS5839 Part 1 standard.
The Fire Isolator Switch provides a secure method of isolating the mains supply feeding a fire system control panel and is crucial for fire system maintenance. The supply can only be isolated by an authorized person, by means of a key lock switch and switching is restricted by key operation. The key is removable in both ON and OFF positions and without the key, a tool would be required to disconnect the power.
A neon indicator is provided to indicate mains present at the switched output. Bold red, durable casing ensures easy visual identification. The unit is supplied in a complete enclosure, which is of a standard single gang format with preformed holes for mounting on a surface or 20mm conduit box.
BS 5839 Part 1 Fire detection and fire alarm systems for buildings – Part 1: Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises is a standard published by the British Standards Institution.
